I have never had the patience to stick to a cleanse. I did the Master Cleanse for only a week and thought I was going to die. I've known people to do it for 30 days...ugh.
I'm a hot yoga enthusiast. I believe it is one of the best ways to cleanse my body of toxins. Not only do the poses bend and twist and squeeze the organs and muscles...moving toxins along, but the sweat also helps. There is much debate about how much sweating really removes toxins. But there is no doubt I feel cleansed when I practice regularly. And believe me, you cannot do hot yoga if drinking a lot, or even regularly.
